Buggles -- "Video Killed The Radio Star" (1979)

This song, which was released in 1979, was a #1 hit in 16 countries -- including the UK, France, Italy, and Sweden. It reached #2 in Germany, but only #40 in the US.

The music video of "Video Killed the Radio Star" was the first video to be shown on MTV, which began broadcasting at 12:01 a.m. on August 1, 1981 (or 8/1/81, if you prefer). MTV's choice of this video was no doubt intended to be ironic, given that the song is about television bringing an end to the golden age of radio.
